Installing Your Hub
Environmental Requirements
Before you install your hub, review the following environmental requirements.
Storage Temperature and Humidity
You can store your hub in temperatures ranging from -4°F to 140°F
(-20°C to 60°C) and humidity ranging from 0% to 80%, non-condensing.
Water and Fluid Resistance
Your hub is for indoor use only and doesn’t meet any salt-spray or water ingress
requirements.
CAUTION
Do not pour or spray any liquids directly onto the product. These liquids can get
into areas where they could damage sensitive electronic components.
Dust and Scratching
Your hub is for use in office and classroom environments only. It isn’t designed for
industrial use, where heavy dust and pollutants can cause malfunctions or impaired
operation. The design is for pollution degree 1 (P1) as per EN61558-1, which is
defined as “No pollution or only dry non-conductive pollution.”
Electrostatic Discharge (ESD)
Your hub meets the requirements of EN61000-4-2 severity level 4 for direct and
indirect ESD. No malfunction or damage up to 15 kV (both polarities) with a
330 ohm, 150 pF probe (air discharge). Unmated connectors meet 8 kV for direct
(contact) discharge.
Conducted and Radiated Emissions
The narrowband radiated electric field from your hub meets the limits for Class B
performance as defined in EN55022/CISPR 22.
